Let's do it that way and then write the solution using algebraic notation. The pants cost $20 and the total cost was $95 so the three sweaters cost $95  $20 = $75. Hence, since 3 sweaters cost $75 dollars the cost of each sweater was $25. I am going to change the problem slightly so that the arithmetic isn't quite so easy and then use algebra to solve it.
The cost for the pants was 20 dollars and each of the three sweaters cost d dollars so the total cost of the sweaters was 3 × d dollars. Thus the total cost was 20 + 3 × d dollars. We know the total cost was 92.36 dollars so
This is the equation I am looking for. In the first problem I subtracted 20 dollars from 95 dollars to determine the total cost of the three sweaters. Yo do the same here. Subtract 20 from each side of the equation to get
or
In the first problem the total cost of the three sweaters was $75 so it was easy to see that each sweater cost $25 since $75/3 = $25. In the current problem you have
and if you divide both sides by 3 you get
or
So each sweater cost $24.12. Now try the algebraic approach on the first problem.
